It’s easy to add highlighting for numbers and other custom strings. This is defined in Properties -> Highlight (1). Example for numbers:

	#Keyword color=1,word=on,rightall=off,case=on,insidetag=off,regexp=on

	(?![a-zA-Z_])[0-9]+.*(?![a-zA-Z_])

	

I don’t think it’s possible to highlight blocks spanning several lines.
